I made up a box 10" square for it, and also made up four slightly smaller ones for the stabilizers.
I found many times I need extra height for the tongue jack to get it on and off the hitch ball, and I also found that the more spread out the stabilizers are the less wobble there is in the trailer, and putting them up on the boxes solved that problem.

We have also found that we need to raise the tongue jack extremely high in order to get the hitch on and off the tow vehicle. I happened to be on Youtube and found a segment from Recreation in Motion. A viewer had several 2 x 4's which were cut where each piece was smaller then the previous. Once nailed together it created a stair-step looking creation. I did not create a stair step. My pieces were all 4 to 6" smaller similar to what I had seen. I centered them all on the 1x6 piece. I am not an engineer, but I thought the support would be better if the wood was centered on the base. We will be trying it out later on today. It's a quick fix and probably won't last long because the bottom 1x6 is the only pressure treated piece. We will eventually purchase an electric tongue within the next several months.

I'll take a picture later on and post it. If it doesn't work, nothing lost. The wood was going to be recycled anyway.

I use a piece of railroad tie about 12" long. I did use one of the red cone jack stands like others have suggested but mine split from the bottom and continued to split about half way up the cone. I had to toss it in the trash.

I carry one of those drive on jacks "Trailer Aid", that allows you to change a flat on one axle by pulling the trailer up on to the wheel on the other axle on the same side. Not liking to carry stuff that doesn't get used much, I use this under the trailer jack wheel when camping. At the house, when the trailer is in storage, I use a concrete block.
